Referring now .to the drawings in detail, the machine embodying thepresent invention comprises asupporting frame Ill on which is mounted abearing frame for a pair of metal rollers l4 and i6 (Figs.'2 and 4).each journalled. at its opposite ends for rotation insuitablebearingscarried by frame I2. Roller I4 is spring pressed towardroller l5 bysprings l8.which are adjusted by threaded. rods LZ imounted. in bracket arms 22 forming a part .of frame. I2..Saidrollershave a peripherally continuous bight relation, during therotation thereof. Therollers I4 and t6 have gears 24- 25, respectively,fixed thereto for rotating said rollers at thesame speed, said, gearsbeing in mesh with each other. A driving gear 28 meshes with gear 26 andis driven .bya pulley 3!} connected by a belt 32 to anelectric motor 34.

When rollers 14 and I6 are rotat-edthey draw oneor more webs W of sheetmaterial therethrough, and in accordance with the present invention theweb Wis marked or printedupon and is cutinto strips of equallength andmore specifically, in the present form of the invention, into lengthsapproximately equal to thecircumference of roller [4. Referring to Fig..'5 the manner of marking and cutting the web is illust ated, and itwill be seen that the web is marked along transverse lines spacedfrom'each other longitudinally of the web,v namely as here shown along linesLl andLZ adjacent the cut edges Cl and G2 at the opposite ends,respectively, ofthe strip S cut from said web. Other marking lines L3,L4, L5, L6, and L! are .appliedduring the operation of roller I4 to theportion of the web constituting said strip S, said lines being, as hereshown, spaced equally from each other along the length of theweb. Themeans for thus marking and cutting the web will now be described.

First, with respect to the marking. means, the

latter comprises a plurality of marking bars 36 which apply the lines L3to L6, inclusive, and a pair of marking bars 38 which apply the lines LIand L2. As illustrated in Fig. 4 said marking bars 36 and 38 are spacedfrom each other peripherally of roller [4 and extend longitudinally ofthe roller, i. e., in a direction parallel to the axis of said roller.As here shown, (Fig. 2) there are a plurality of sets of said markingbars, one for each of a plurality of webs W which is fed between thecompanion rollers l4 and I6. As illustrated in Fig. 2 roller I4 isprovided with a plurality of peripheral grooves 48 spaced from eachother longitudinally of the roller to accommodate the thickened portion42 formed on the web when the latter is folded as illustrated in Figs. 5and 5A.

As all of the bars 36 and 38 are of the same construction, a descriptionof one of the bars 36 will be sufficient, reference in this connectionbeing had to Fig. 6. Each marking bar is formed of a strip of suitablemetal, for example, brass, and is provided with a plurality oflongitudinally spaced projections 42 so that the lines marked by the barare dotted or interrupted lines as illustrated in Fig. 5, thus reducingthe quantity of marking material applied to the web by the marking barsso that when the lines of stitching are applied, the marking materialwill be sub stantially invisible. The intermediate part; of each bar isprovided with a portion 44 devoid of projections 42, said part 44 of thebar being located at the peripheral groove 46 acros which the barextends. Each bar 36 and 38 is positioned in a slot 46 in roller l4adjacent the outer I periphery thereof and is movable in said slotradially of the roller. The bar is urged outwardly in-a radial directionby a pair of springs 48 positioned in holes 58 extending inwardly fromthe outer surface of roller I4. The outward movement of bar 36 islimited by the screws 52 the heads of which engage the adjacent endportions 54 of the bar. It will be understood that screws 52 permit theinward movement of bar 36 against the pressure of springs 48 and allow alimited outward movement of said bar due to the action of said springs.

.As illustrated in Fig. 6, the head of each screw 52 is arranged toengage the adjacent edges of longitudinally adjacent bars 36, when, asdescribed herein, there are a plurality of sets of marking bars. Bars 38are mounted in the same way as bars 36 but as illustrated in Figs. 2, 4,and are disposed closer to each other than to bars 36 and are disposedat opposite sides of the cutting member 56 so that as the web is cutinto strips by said cutting member 56 line L2 is applied to the web inadvance of the action of cutting member 56 so that line Ll is applied tothe web adjacent the leading end thereof after the strip SI hadpreviously been cut from the web. More particularly, referrin to Fig. 5it will be observed that line L2 applied to strip S cut from the web Wis applied to the web at the portion thereof forming said strip by oneof the marking bars 38 just before the cutter member 56 engages the weband cuts the same along the line C2 after which the other marking bar 38engages the web at the strip forming portion S2 thereof and applies onthe latter the line Ll. It will be understood that this marking andcutting process is continuous at regular intervals alon the length ofthe web W while the latter is fed between the'rollers. It will beunderstood, also, that while the web passes between the rollers bars 36act thereon to apply to each strip forming portion the marking lines L3to L1, inclusive.

The cutter member 56 is held in a groove 58 adjacent the outerperipheral surface of roller l4 by screws 68 the heads of which engageadjacent end portions 62 of longitudinally adjacent cutter members 56there being as here shown a cutter member 56 for each set of markingbars 38. It will be understood, however, that one cutter member can beutilized instead of a plurality of cutter members 56 in which case thesingle cutter member will be of sufficient longitudinal extent forcooperation with a plurality of sets of marking members.

As illustrated in Fig. 10 the marking members 38 normally extendoutwardly beyond cutter member 56 and, it will be understood that eachmarking member 36 likewise extends radially outwardly beyond cuttermember 56 whereby to permit marking members 36 and 38 to engage theink-applying roller 64 without engagement of the latter by the cuttermember 56 during the rotation of roller l4. Further, it will beunderstood that as the marking members are brought into engagement withthe ink-applying roller 64 the outer surfaces of the projections 42 ofthe marking members engage said roller resiliently by reason of thepressure of springs 43 and that in passing said ink-applying roller themarking members 36 and 38 are moved inwardly toward the center of theaxis of roller l4 against the pressure of the companion springs 48. Inkis applied to the roller 46 by a transfer roller 66 which, in turn hasthe ink applied thereto by the supply roller 68. Said rollers 64, 66,and 68 are mounted for rotation in an auxiliary frame 18 supported bybracket arms 22. Roller 68 is driven by a pulley 12 rotated by a belt 14driven by a pulley T6 fixed to the shaft of roller l4 and rotatedthereby. The set of rollers 64, 66 and 68 is of the type utilized inprinting machines and as usual roller 68 is formed of metal whilerollers 64 and 66 are provided with outer layer of resilient material,all as well known in the printing art and, therefore, requiring nofurther description. Ink may be supplied to roller 68 from the box 18 inwhich roller 68 operates, or in any other suitable way. 7

From the above description it will be apparent that durin the rotationof rollers 14 and I6 they draw the web W therebetween and that whilesaid web passes between said rollers l4 and I6 it is marked and cut intostrips of predetermined lengths, the lengths of the several strips beingequal to each other and substantially equal to the circumference ofroller M. It will be understood that marking members 36 and 38 are movedinwardly against the pressure of springs 48 when each of said members ispositioned, during the rotation of rollers l4 and I 6, at the bight ofsaid rollers, it being noted in this connection, that springs I8 are, ofcourse, much stronger than spring 48 and hold roller l4 firmly againstthe web W or other work which passes between the two rollers. Further,it will be noted that roller l4 can move upwardly, if such movement isrequired when the work is engaged by the cutting members 56, suchmovement, if any, being slight so that gears 24 and 26 always remain inmesh.

Thus, the mounting of marking members 36 and 38 for movement radially ofroller I4 not only permits said marking members to engage theink-applying member 64, but also allows for the engagement of themarking members with ttheiwork without subjectingtsaidrmarking membersitoctheqicomparativelyir high pressurefexerte'd on-roller ltbyrSprings 8."Moreover, in the case of one of themarkingmembersffl, namely the toneat theleft of the cutter member 56' (viewing Figs-4 and the normal'projection ofsaid marking member "outwardly beyond the cutter 'member 56enablessaid markingmember to engage theend. of the-web immediately afterthe latteris cut by the cutter memberrfifiand holds .feedingactionof-rollers Mand it.

A chute'BU is provided atthe delivery end of rollers l4 and I6.forguiding the'strips cutfrom the web-W to. a receiving receptacle (notshown). As indicated in Fig.2 .guideSWSZ -are provided on table 8 l,which forms. a part of. frame -lli, for guiding the webs W to the bightbetween rollers M and I5 and. to thecorrect point. longitudinally of theroller Mlfor engagement in correct relation with the cutter and markingmembers.

In accordance with the present invention, as indicated above, thepresent machine .is constructed and operates'to fold a flat webWl intofolded form of .the web W illustrated inFigs. 5 and 5A, the latterbeing-cutinto strips of suitable lengthier makingbandoliers. According-A ly, as here shown, the present machine comprises nleansfor folding theweb-WI longitudi- .nally thereof .intothe cross-sectional formationillustrated in Fig, 5A. The means provided-for this purpose comprises a:pair of calender 'rolls 8% and -88 journalled for rotationinbearingsformed in a frame member w 95' mounted on 117118 supporting frame it.The folding means -:also

includes a folder .92 of any suitable construction, which many-are-welhknown, through which the flatwveb W! passesand which folds the webinto the form illustrated; in --Fig. "5'A,the

calender rolls 8%; and 88 serving 1 -tocrease the folded side edges- 52aandAZblFig. 5A) To 'improve the creasing or ironing effect of thecalender rolls, roller 86 is'preferably heated and for this purpose isprevided withia gas burner (not shown) dispesed internally thereof, in awellknown way, andsupplied with :gas through a supply pipe "94. Asheated calender 'rolls are well-known and do not per *se form--partofthe present invention further description of said-rolls is unnecessary.It may be noted, -however,"that means including ascrew-threadedrod'rhifi Joperable by a hand wheel 98*areprovided'att'each end of the calender rolls'for-ad'justingthe-ipressurethereof on the folded web'whilethelatter therebetween.

Rollers Stand 88 are driven in timed relation to rollers M and l5preferably "at such speed that the feed ofthe web 'bylthe calender rollsis substantially equa1"to"the speedof the .webby the rollersltand'lii.Ferthistpurpose'roller i3 is connected to and drives roller 83' by meansof sprecliet wheels Hit and Hi2 on the shafts of rollers it and "t5,respectively, said sprocket wheels being connecte'dby a sprocket chain103. .Calenderroller 85 isdriven from calender roller 38 by the meshinggears IM and" W5 fixed to the shafts of said calender rollers,respectively, there being a set of thesegears atea'ch end of thecalender.

Thus, in'the operation of the: machine, one or more flat webs WE aresupplied to thewmachine and l are drawn continuously through the folderi9 2 :by .the calender rolls can-d .are;.ironed by ,the

The machine operates continuously tofoldthewebrand'to mark 'and cut the sameall substantiallyrinzone:operation.

It will be understood :that after the strips .are

marked and cut away :from the 'webthey 'are stitched along the lines:marked on saidfstrips andthat-byrreason of :theaccuracy of this machinein locatingthe marked lines'onthe'strips, the stitching of-the'stripswhen conformed to said :marked lines is "very accurate, this"being very. important :in' the manufacture of numerous articles andespecially fbandoliers in which it is important that the pockets formedbetween successive lil'lESlOf stitching. be of correct width conformingtormilitary specifications.

In Fig, 11" there .is illustrateda modification'o'f the invention. Ashere shown, provision"v is made l4 since 'by .mOVingfthe cuttermember"56 inwardly and outwardly? attheproper .timesduring therotationof roller M, said cutter member will clear the ink-applying roller 1'64without engagingthe latter and'can'rbeprojected beyond the outersurfaces'of the marking mer'nbersfor engaging" the "web eatthe" bightbetween the companion rollers. .As illustrated, cutter member has alowersinclinediedge' )8 which engages the inclined'upper surface I I'llOfTthG groove" 58 so that whencutter-- member 56" is moved 1on-.gi-tudinally-of said groove itis projected radially woutwardlyif moved-to -the right (viewing Fig.

111) .and it is. projectedradially inwardly if moved to the left.(viewing .Fig. :11). Any .suitable means may be provided for thusmovingcutter member 56. in timed relation to the rotation of roller .I4as,.for example, cams H2 andJM properly "designed as will be readilyunderstood td'engage the adjacent-ends H6 and H8 of cutter memberEB'for-effecting the necessary movements of cutter member 56 longitudinallyof groove 58. 'It" will be understood that cams H2 and I M arestationary and are slidably engaged by the ends'llfi and H8,respectively, of said cutter member. Further, it will be understoodthatcams- I12 and H4 are the reverse of each other so that one camallows the longitudinal movement of the cutter member when the latter isacted upon by the other cam for moving the cutter member in" the properdirection longitudinally in the groove 58'.

As indicated above when the cutter member is not movable radially of theroller, the marker members-36' and"'38 are movable radially of theroller- M from projected positions outwardly the cutting edge .of cuttermember 56 to retracted positions in whichthe outer surfaces of markermembers BBta-nd 3B lie flush with the outer surface ofroller 'l Lzassforexampleto the position of the" right hand marker member 38 shown in'-Fig "10. lt'will beunderstood that each of the marker members-36 and'38"are moved into the retracted positions atthebight of rollers l4 andH5. 'When thermarker member isnotin the form of the'narrowbarillustrated herein but is of substantialwidthg. such: as'for.exampleaprinting plate, such marker member need not be mounted formovement radially of the roller l4 and. the outer surface of theprinting plate can be positioned a short distance outwardly beyond theouter periphery of roller l4 since the pressure between the rollers l4and I6 would, in that event, be distributed over a sufficient area ofthe marking member, in this case the printing plate, to prevent injuryto such marker member.

It is within the scope of the present invention, however, to mount themarker members for radial movement, as described above, when the latterare wider than the bars 35 and 38 or when the cutter member is radiallymovable.

While we have shown and described the preferred embodiment of ourinvention, it will be understood that the latter may be embodiedotherwise than as herein disclosed and that various changes in thedetails of construction and in the arrangement of parts may be made inthe present described embodiment. For example, instead of a singlecutter member, a plurality of cutter members can be mounted on roller Min equal or unequal spaced relation peripherally of the roller so thatduring the rotation of said roller strips of equal or unequalpredetermined lengths are cut from the same web. Thus, for example, twocutter members can be mounted on the roller in peripherally spacedrelation either diametrically opposite each other, for cutting twostrips of equal length during one revolution of the roller, or at adifferent peripherally spaced relation, for cutting two strips ofunequal length during one revolution of the roller. Further, it will beunderstood that the machine can cut and mark materials and articlesother than sheet materials or articles formed from material. Also, itwill be understood that it is possible to utilize certain parts of themachine without others. Accordingly, we do not wish to be limited to theinvention as herein shown and described except to the extent which maybe required by the scope of the appended claims,
